BIOS firmware archive for a laptop built on the Wistron board 15341-1, with the extra token 91N85 in the name, likely a board part identifier. The SklKBL prefix points to the Skylake and Kaby Lake Intel platform this board supports. Wistron uses this five-digit numbering with a revision suffix for designs it builds for brands such as Dell. Unpack the RAR and compare the image size with the SPI flash chip before programming. Confirm that 15341-1 is printed on the PCB and save a backup of the original chip first.
